Given numbers are 27, 66, 63, 57

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(27, 66) = 594

GCD(27, 66) = ( 27 x 66 ) / 594

= 27 / 66

= 27

Step2:

LCM(3, 63) = 63

GCD(3, 63) = ( 3 x 63 ) / 63

= 3 / 63

= 3

Step3:

LCM(3, 57) = 57

GCD(3, 57) = ( 3 x 57 ) / 57

= 3 / 57

= 3

So, Greatest Common Divisor of 27, 66, 63, 57 is 3
